Audi Repair Questions? Ask a Mechanic for Answers ASAP
Thank You for choosing Just Answer for your query. Yes, I can help you.
This one "bites" more techs than about any procedure I can think of. It is simple , but ambiguous. Marking it with paint is GOOD advise. I have NEVER heard of one "jumping" though. Typically they are incorrectly installed after associated repairs.
Here is the image you requested. Be sure to count exactly 16 pins between the two marks.
I hope that I have answered your questions and addressed your concerns. Should you have any further questions for me, please do not hesitate to ask. I want you to be 100% satisfied with my answer.

Yes, and no.
This IS a GOOD image the marks are the small square holes (smaller than the image) where the gear mounts on the shaft. The lines that extend to the location between the points of the gear, displays there orientation, so you no not think they line up with a point on the gear.
You get it?
Let me know.
The marks DO point up as indicated. I am not sure what is going on based on your explanation. Perhaps you could tell me how this all came about because they DO NOT normally "jump time" between the intake and exhaust.
Do you have the special tool to collapse the adjuster? This is a required tool. You can get them on E-bay for less than $15. Also if you buy a new adjuster, it comes with one installed. I ask because you say "up or down at TDC?". It's not a matter of "up or down", it's more like in the middle. If you have been taking it in or out without the tool, it could very well be damaged. Also, if it looks worn, I suggest you replace it.
Was/is the adjuster guides damaged?
Is it possible that someone has replaced some parts (incorrect) before you getting the vehicle?
Perhaps if you told me how this all came about, it could further shed some light on the cause if this condition. I have set up MANY of these cams this way and NOT had any problems.
BTW, in your first post you indicated an AWM motor, should not that be an AMB motor? AMB was phased in 2002, you said this was a "2004 audi a4 1.8 turbo awm". Can you shed any light on this?
"sight unseen" What does that mean? Was the vehicle apart? Did it run when it came to you? I do not understand.
OK, VW kept the AWM.
Are you SURE you have the correct marks??? Every image I can find in VW or Audi shows the lobes for #4 cylinder "UP", valves "CLOSED".
Is this the marks you are going by???
Based on your statements thus far, I believe you got this head dis assembled or mis assembled and the exhaust and intake cams are switched.
Pretty darn sure. If I read your last statement about mark and lob orientation, this matches the location of the orientation if you look at the above image.
Don't worry about the adjuster going up and down.
Let me know!
Sorry I "misplaced" you. Have you made any progress? Right, can't mix them up, spaced that. I would like to get on apart and inspect, but have not had the chance.
Have you removed the gears from the cams? I have heard of the key way shearing, but never experienced it.
You still have not told me what "sight unseen" meant or the reported story of how this all came about and how you received the vehicle? Is this even the same cylinder head and cams that were in the vehicle when "whatever" happened?
